Short answer: the Monster Bambox, though neither ranks well in its class. It ranks #76 of 105 boombox speakers by sound quality, rated 2.8/5, at $219; the Turtlebox Gen 3 ranks #97, rated 2.1/5, and costs $430, which makes this an easy call rather than a real tradeoff. Both are rated below 3.0/5 among the 105 boombox speakers, so if sound quality matters, consider the Tribit Stormbox Blast instead, ranked #2 at $179.99.
The Monster Bambox is the better-sounding, longer-running option. Rated for up to 48 hours from a long life LiFePO4 battery, with IP67 waterproof and dustproof rugged housing, Auracast linking, a 30 watt USB-C charge out, a microphone input, app controlled EQ presets and 256 RGB lights. It is rated for 48 hours of battery against 25 for the Turtlebox Gen 3. It has an adjustable EQ, which the Turtlebox Gen 3 lacks. Watch for: No measurements or reviews, so its rating is estimated, and the 300 watt figure is peak power (100 watts RMS).
What the Turtlebox Gen 3 does well: Waterproof (IP67, and it floats) and crushproof, with stainless steel hardware and quality amplifier parts inside. Watch for: Sounds basically identical to the original and the Turtlebox Gen 2: each generation mainly added features, not sound quality.
Buy the Monster Bambox. It is rated higher for sound quality than the Turtlebox Gen 3 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
